When creating the UI for the SQL view, it is now possible to set a specific Parent Menu which will be used when creating the UI Menu for the report itself. The default value will be the `SQL Reports` menu.
Also, added the explanation on the `CONFIGURE.rst` file to have the description updated.
- move menu and action in according view file
- use new sql_request_abstract menu entry for SQL views configuration
- Use sql_request_abstract primary tree view
- Use sql_request_abstract primary form view
- move has_grouped_changed in sql_request_abstract module
- improve demo data
- add default count value to display in pivot, if no pivot_measures are defined ;
- set widget handle to sequence field
- reorder fields in tree view and add optional hide for some fields
- simplify : make field_description field required
- improve : add optional='hide' and 'show' on tree visibility
- replace obsolete base.menu_board_root by spreadsheet_dashboard entries
- update translation
this commit allows specifying the group operator for each field. This functionality was originally included in a seperate module "bi_sql_editor_aggregate" in version 12.
